Windows and doors in Wotton
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Polesden Lacey (about 3 miles north) are a reminder that the area around Wotton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St John the Evangelist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as The Priory CofE Voluntary Aided School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Gomshall station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How we handle window mastic in Wotton
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a 12-month guarantee on the work. If you have black, perished sealant on frames and sealant in the wrong colour for the frame, we can help, on patio & French doors, uPVC windows and timber windows & doors alike.
Homes in small places like Wotton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Wotton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children

How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before any work starts. It won’t solve:
- A sash or casement that won’t close properly
- Damp problems in the wall away from the window
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
What we seal
- Window sills
- Composite doors
- Timber windows & doors
- uPVC windows
- Aluminium frames
- Patio & French doors
How to look after the new joints
Looking after new joints is easy:
- Keep drainage slots and sill grooves clear
- Avoid harsh chemicals near the mastic
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
Silicone cannot normally be painted, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Wotton: your questions answered
Do you cover Wotton for window mastic?
Yes, Wotton is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Gomshall station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
How many windows can you do in a day?
Allow a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

What else we do in Wotton
Why act early in Wotton
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Wotton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.
